Step-by-step explanation:
Calculate the slope m using the slope formula
m =
with (x₁, y₁ ) = P(- 2, 2) and (x₂, y₂ ) = Q(2, 2)
m = = = 0 ← slope of line PQ
This indicates the line PQ is horizontal and parallel to the x- axis with equation
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (- 2, 2) and (2, 2) with y- coordinates of 2
Thus y = 2 ← equation of line PQ
The way u wrote it doesn't make sense
but u should combine like terms. then multiply regularly. hope this helps
Answer:
x = -2/3; x = 5/2.
Step-by-step explanation:
6x 2 - 11x - 10 = 0
Use the 'ac' method:
6 * -10 = -60. We need 2 numbers whose product is -60 and whose sum is -11.
That would be -15 and +4. So we write:
6x^2 - 15x + 4x - 10 = 0 Factor by grouping:
3x(2x - 5) + 2(2x - 5) = 0
(3x + 2)(2x - 5) = 0
x = -2/3; x = 5/2.

Step-by-step explanation:
When rotation is 180° or 360°, the direction is immaterial. The result is the same no matter which direction you go.
notes:
c= Colin
s=Sara
g=Gordon
c=g+36 (1)
c : g
5 : 1
c/g=5
c=g*5 (2)
=> from statement (1) => g*5=g+36
5g-g=36
4g=36
g=36/4=9 g=9 sweets
=> from statement (2)=>c=5*9=45 c=45 sweets
s : g
2 : 1
=>s/g=2/1
=> s=2g
s=2*9 s=18 sweets
sum=c+s+g
sum=45+18+9=72 sweets
